      SERVER-51556 implemented $substrBytes expression in SBE, which enabled Aggregation.IdentityView.ExpressionObject mongo-perf/testcases/pipelines.js testcase to run in SBE, which caused 40% perf regression.

      This ticket needs to ensure that as part of SPM-3243 we recover this perf regression.
